Answer:

Step-by-step explanation:

opposite angles are equal

∠PTQ = ∠RTS

x + 28 = 2x + 16

combine similar terms

28 - 16 = 2x - x

x = 12

∠PTQ = x + 28 = 12 + 28 = 40

∠RTS = 2x + 16 = 2(12) + 16 = 40

∠PTR = ( 360 - 40 - 40 )

∠PTR = 140

Dafna1 [17]

Answer:

Answer is given below with explanations. 

Step-by-step explanation:

$given \: \: l = 5x - y \: and \: \: b = x + 4y \\ area \: of \: rectangle \:= l \times b \: sq.units \\ = (5x - y)(x + 4y) \\ = 5 {x}^{2} + 20xy - xy - 4 {y}^{2} \\ = 5 {x}^{2} + 19xy - 4 {y}^{2} \\ perimeter \: of \: rectangle \\ = 2(l + b) \\ = 2(5x - y + x + 4y) \\ = 2(6x + 3y) \\ = 12x + 6y$
